Look at the initrd, and the linuxrc script.

It probably contain some code to find the cdrom and mount it by doing something like this:

	for x in hda hdb hdc hdd                        
        		mount -t iso9660 /dev/${x} /cdrom                                         
		        if [ "$?" == "0" ]                          

If the Kernel support NFS, you can probably replace the first part where it looks for the CDROM with code that mount an NFS share SLAX files in it.
